核空气净化系统高效空气粒子过滤器旁通阀选型试验研究

The Experimental Research on Bypass Valve Selection of Nuclear Air Purification System HEPA Filter

通过使用核空气净化系统高效空气粒子过滤器泄漏分布测试试验平台,分别对带有三种不同型号旁通隔离阀的高效空气粒子过滤器进行了过滤效率测试,通过分析测试结果,完成了旁通阀型号初步选择,并进一步进行了现场过滤效率测试,最终选取了符合设计要求的旁通阀。

By using the experimental platform of nuclear air purification system HEPA filter leakage distribution,the test was respectively carried out for the HEPA with three different types of bypass isolation valves.Through the analysis of the test results,the preliminary selection of the bypass valve model was completed,and then,the on-site filtration efficiency test was conducted.Finally,the bypass valve which met the design requirements was selected.
